. 15 Claims ((31.105-364) adapted to withstand the severe conditionsof mine service; a car which will endure the shocks and strains of uneven road beds; which will support heavy material to full capacity lading and which is especially resistant to torsional strains at the points of union between the lading body and the axle pedestals.

Another object of the invention is to provide an inexpensive body construction largely of plate metal but having incorporated therewith or attached-thereto certainstrengthening' and, or,'-reinforcing, elements so arranged as to obtain maximents. I

Another object is in'the provision of a certain type of longitudinal beam or sill'used in conjunction with a plurality .of transverse supporting belts or straps,' in a manner of assembly which obtains suitable fit'and engagement of parts here-.

tofore diflicult and expensive, if not actually impossible, to obtain.. V

Still another object'is to provide a stub-axle as sembly and mounting therewith, in alternative forms of solid .roller, or Timken; bearings between the axle and wheel in which, when Timken or other conical roller bearings are used, an adjusting device of durable construction may be incorporated; the means for making the adjustment being easily accessible and operable,- without requiring special tools.

Other objects will be in part obvious and. in

' part pointed out particularly hereinafter.

The-invention accordingly consists in the various features of construction, arrangements of parts and combinations of elements which will be exemplified by the description hereinafter set forth and the scope of the application of which will be indicated. in the appendedclaims.

In the drawings:

Figures 1 and 2 are complemental views in side elevation of a mine car embodying the. invention.-

Fig. 3is a view in bottom plan of one half of the car as shown in Fig.2.

Fig.4 is a View in end elevation of the same.

Fig. 5 is a view in cross section taken through flanges 12 projectoutwardly. their ends these sills are connected to end sill members 13 by angle members 14; The end sills are preferably of metal plate having lower flanges 1-5 directed toward the car and upper flanges 16 extending from the car and constituting draw-bar members suitably recessed asindicated at 1'7. Bumpers are attached to the end sillsas indicated at 18 and 19.

The presentv invention 1 is applicable to cars using the lift end gate fordischarging, or to cars of the rotary dump type; The drawings show a lift end gate 20 pivoted at 21 and by reason of the mechanism at the gate end of the car is slightly different from the construction just described difi'erencesin detail are not considered important to an understanding of the present invention.

The side sills are also connected by a central 'in line with the bulb edges of the sills.

' Side lading bottoms constituted by flare-sheets I 1,962,723 UNITED STATES PATENT OFFICE end gate construction the draw-bar and bumper ,75 which is at the fixed wall end of the car. These 24 are riveted to the top flanges 12 of the sills and side walls 25 extendjupwardly fromthe outer edges of the side lading bottoms either as a part thereof or as separate jpieces suitably joined there with. The car shown in the drawings has a fixed end wall 26 ofv plate metal'and a movable end gate20' as previously'described. In rotary dumpcar construction an end wall similar to' 26 is'applied at the opposite end of the car; In cars .for end dumping operationaslope sheet 27 is applied to the central lading bottom at the dump end of the car soas to facilitate the discharge of the lading. Obviously this is omitted in rotary dump car construction.-

The car body including the side walls and side lading bottoms, constituting the wings, and the sills and central lading bottom, is reinforced by a series of spaced transverse belts or straps certain of which, a indicated at 30, are intermediate straps which pass entirely around the body from the top of one side wall to the top of the opposite side wall. Other belts 31 preferably extend from the tops of the side walls along the under-face of the side lading bottoms and down against the cute erfaces of the webs of-the side sills. At the gate end of the body a tranverse belt 32'passes from the top of one side wall around the body to the top of the opposite side Wall. The belts 30 and the end belt 32 are riveted at intervals along the side walls and to a certain extent under the side lading bottoms and then descend 'obliqu'elyv as indicated at 33 and are formed around the bulb edges of the sills as shown clearly at 34 in Fig.5. Preferably, they are riveted along the central lading bottom and it will be noted that the bulb" lid edge provides a convenient means for making a close fit of the belts. It will also be noted that no fillers are required between the belts and the central lading bottom. The belts with diagonal reaches from the side lading bottoms to the central lading bottom give the effect-of a reinforcing gusset or strut for the side wings while the belts or straps 31 having their lower ends riveted to the sills and their reaches riveted to the side lading bottoms and ,the side walls, reinforce and maintain the wings by direct association with the substantial sill members.

The car shown in the drawings is supported at four zones, two at each of the opposite sides of the car directly under the lading wingaand each of the supports comprises a construction in which a four-point support is efiected due to the specific construction and arrangement of parts as now to be described. Secured to the outer surfaces of the webs of the side sills 10 by rivets d2, or other suitable fasteners, are. inner axle bearings 40, castings in the instance shown, which are fitted between the flanges l2 and the bulbs of the sills 10, as clearly shown in Figs. 5 and 6. The bearings 4c are apertured to receive the enlarged inner ends 51 of stub axles 5c; the apertures being of such form as to permit a clearance 40 between the axle and bearings 40 to compensate for lrregularities and unevenness of track grades with out imposing undue strains on the car.

The axles 50 are mounted in wheels 60 and the outer end portions 52 thereof are positioned in the central portions or bearing portions 41' of the outer axle bearings 41, the central portions 41' being \provided with apertures of such shape as to provide a clearance 52.

The outer axle bearings 41 are elongated castings and each includes arms 45 extending in opposite directions from the central portion 41' and having their end portions underlying successive belts 30 and 31 and provided with attaching flanges 46 which receive bolts '70 extending through the flanges 65 of wheel housings 61 covering the whee1s'60; the wheels extending into openings formed in the side lading bottoms of the car. The housings 61 are also formed with flanges 62 secured to the side walls 25 of the body by rivets 63 and with attaching flanges 64 connected to the flanges 12 of the side sills by the rivets 43. At points other than those which take the bolts '70, the wheel housings are secured to the side lading bottoms by rivets '71, a shown clearly in Fig. 3.

Thus the curved wheel hood and longitudinally extending outer axle bearing 41, the straps 3c and 3-1 and the body pieces are tied into an integral and strongly reinforced structure. Not only are the metal plate lading bottoms and side walls strengthened but the strengthening means are tied into the sills by the engagement of the straps 31 with the webs of the sills and the engagement of the wheel hoods with the flanges of the sills.

If the wheeled axle is of the solid roller type as shown in Fig. 6 the wheel hub may be extended as shown at 81 owing to the spacing between the axle bearings. A cotter pin 82 is introduced through apertures 83 in the extended hub and cooperates with a flange 84 through the intermediary of a washer 85 to limit relative lateral movement of the wheel and axle. The hub may be filled with lubricant through apertures 83 which are suitably plugged when filled. The rollers are indicated at 86.

Where cone bearings are used as shown in Fig.

weaves 5 of the drawings the axle is held in position by an end flange engaging a shoulder 91 of the inner axle bearing. A collar 92 is fixed on the axle adjacent the inner a'xle bearing and a collar 93 is loose on the axle toward the outer end. Between the collar 93 and the axle bearing d1 an adjusting nut is threaded on a reduced end of the axle so that by rotation thereof the loose collar 93 may be moved toward the fixed collar 92 bringing together spaced bearing races mounted on the axle. Cooperating spaced bearing races are adjusted in the hub of the wheel 60 and conical rollers are arranged between the races. It will be noted that the adjusting nut is protected to a degree by the outer axle bearing casting but is exposed, nevertheless, in position where it may be operated by an ordinary wrench. No sleeves v are required between the nut and loose collar which eliminates an objection to prior constructions.

Heavily laden mine cars throw exceptional torsional strains onto the connections between the axle assemblies and the body, particularly in going around curves. The flanges of the wheels cause the axles to conform to the curvature of the tracks while the tendency of the heavily laden body is to continue in the direction it was going. The present invention comprises a simple and relatively inexpensive arrangement of parts admirably suited to the withstanding of such strains and to the other strains and stresses incident to the loadingunloading and carrying of heavy materials.

It will also be obvious that the present con-.

struction provides for supporting the car'body by spaced pairs of axle bearings supported by stub axles, the outer bearings being arranged beneath the side lading bottoms or side floor portions of the car body and being connected to the latter at widely spaced-points, this arrangement in cooperation with the inner and outer bearing members providing for a four-point support at four zones ofthe car body. More specifically, the

outer axle bearings are connected to the body through body stiffening elements in the form of belts, certain of which extend down the sides of the car and under the central lading bottom while others extend down the car sides and terminate at and are connected to the body side sills. Each of the stiffening elements underlies the side lading bottoms, as clearly shown in the drawings.
